2.
Mount the driver on the baseplate. Use applicable bolts and hand tighten.
3.
Install the coupling.
See the installation instructions from the coupling manufacturer.
4.4 Pump-to-driver alignment
Precautions
WARNING:
•
Misalignment can cause decreased performance, equipment damage, and even cata-
strophic failure of frame-mounted units leading to serious injury. Proper alignment is
the responsibility of the installer and the user of the unit. Check the alignment of all
drive components prior to operating the unit.
•
Follow the coupling installation and operation procedures from the coupling
manufacturer.
•
Failure to disconnect and lock out driver power may result in serious physical injury or
death. Always disconnect and lock out power to the driver before performing any in-
stallation or maintenance tasks.
•
Electrical connections must be made by certified electricians in compliance with
all international, national, state, and local rules.
•
Refer to driver/coupling/gear manufacturer's installation and operation manuals
(IOM) for specific instructions and recommendations.
4.4.1 Alignment checks
When to perform alignment checks
You must perform alignment checks under these circumstances:
•
The process temperature changes.
•
The piping changes.
•
The pump has been serviced.
Types of alignment checks
Type of check
When it is used
Initial alignment (cold alignment)
check
Prior to operation when the pump and the driver are at ambient tempera-
ture.
Final alignment (hot alignment)
check
After operation when the pump and the driver are at operating tempera-
ture.
Initial alignment (cold alignment) checks
When
Why
Before you grout the baseplate
This ensures that alignment can be accomplished.
After you grout the baseplate
This ensures that no changes have occurred during the grouting process.
After you connect the piping
This ensures that pipe strains have not altered the alignment.
If changes have occurred, you must alter the piping to remove pipe strains
on the pump flanges.
Final alignment (hot alignment) checks
When
Why
After the first run
This ensures correct alignment when both the pump and the driver are at
operating temperature.
